I think Ram's have a spotty rep for transmissions but then again, I have never owned one.
And there you have it!
That said, I used to say the same about dodge/ram trans based on not actually owning them. Now I own one. It's the best truck I've ever had. Not even close. Including a Tundra and a Tacoma, a pile of Fords, and one Chevy. Trust me, one Chevy was waaaay more than enough.
